I lost interest in this entire thing a little while after working on the website, it is why I have no domain name yet and why there are still copyrighted pictures all over the place (many of them are not copyrighted, btw). My customer base, which dwindles down like you wouldn't believe in the winter, has come solely from word of mouth. That and my involvement on a local tennis website ( www.kctennisplayers.com ).

They're all copyrighted, even if the images aren't watermarked, believe it.

Sometimes it's just hard to prove copyright, but the original creator/capturer has their usage rights covered, and using these images IS a violation of that copyright, end of discussion. Like i said before, even if these are available for public usage under something like a creative commons license, it's not for use in a website used to generate revenue, as yours is.
